Bomb Suspect Acknowledged Role

WASHINGTON (AP) -- Two U.S. officials say the surviving suspect in the Boston bombings acknowledged his role in the attacks to FBI investigators. But the officials say this occurred before authorities advised him of his constitutional rights, including the right to consult with an attorney and not to incriminate himself.

It was not clear whether the admission by Dzhokhar Tsarnaev (joh-KHAHR' tsahr-NEYE'-ehv) would be admissible in a criminal trial, since it came before he was read his Miranda rights. It's also unclear whether prosecutors would need the admission to secure a conviction since physical evidence has already been uncovered in the investigation.

The officials spoke on condition of anonymity because they were not authorized to discuss the ongoing case.

Tsarnaev's two lead defense lawyers did not immediately return phone and email messages.
